How nanotextured interfaces influence the electronics in perovskite solar cells
Dilara Abdel, Jacob Relle, Thomas Kirchartz +6
Perovskite solar cells have reached power conversion efficiencies that rival those of established silicon photovoltaics. Nanotextures in perovskite solar cells scatter the incident…
Physics-Guided Sequence Modeling for Fast Simulation and Design Exploration of 2D Memristive Devices
Benjamin Spetzler, Elizaveta Spetzler, Saba Zamankhani +4
Modeling hysteretic switching dynamics in memristive devices is computationally demanding due to coupled ionic and electronic transport processes. This challenge is particularly re…
Numerical analysis and simulation of lateral memristive devices: Schottky, ohmic, and multi-dimensional electrode models
Dilara Abdel, Maxime Herda, Martin Ziegler +3
In this paper, we present the numerical analysis and simulations of a multi-dimensional memristive device model. Memristive devices and memtransistors based on two-dimensional (2D)…
Forward lateral photovoltage scanning problem: Perturbation approach and existence-uniqueness analysis
Giuseppe Alì, Patricio Farrell, Nella Rotundo
In this paper, we present analytical results for the so-called forward lateral photovoltage scanning (LPS) problem. The (inverse) LPS model predicts doping variations in crystal by…
The Role of Mobile Point Defects in Two-Dimensional Memristive Devices
Benjamin Spetzler, Dilara Abdel, Frank Schwierz +2
Two-dimensional (2D) layered transition metal dichalcogenides (TMDCs) are promising memristive materials for neuromorphic computing systems as they could solve the problem of the e…
A weighted Hybridizable Discontinuous Galerkin method for drift-diffusion problems
Wenyu Lei, Stefano Piani, Patricio Farrell +2
In this work we propose a weighted hybridizable discontinuous Galerkin method (W-HDG) for drift-diffusion problems. By using specific exponential weights when computing the p…
Impact of random alloy fluctuations on the carrier distribution in multi-color (In,Ga)N/GaN quantum well systems
Michael O'Donovan, Patricio Farrell, Julien Moatti +3
In this work, we study the impact that random alloy fluctuations have on the distribution of electrons and holes across the active region of a (In,Ga)N/GaN multi-quantum well based…
Numerical analysis of a finite volume scheme for charge transport in perovskite solar cells
Dilara Abdel, Claire Chainais-Hillairet, Patricio Farrell +1
In this paper, we consider a drift-diffusion charge transport model for perovskite solar cells, where electrons and holes may diffuse linearly (Boltzmann approximation) or nonlinea…
Data-driven solutions of ill-posed inverse problems arising from doping reconstruction in semiconductors
Stefano Piani, Patricio Farrell, Wenyu Lei +2
The non-destructive estimation of doping concentrations in semiconductor devices is of paramount importance for many applications ranging from crystal growth, the recent redefiniti…
Multiscale simulations of uni-polar hole transport in (In,Ga)N quantum well systems
Michael O'Donovan, Patricio Farrell, Timo Streckenbach +2
Understanding the impact of the alloy micro-structure on carrier transport becomes important when designing III-nitride-based LED structures. In this work, we study the impact of a…
Tetrahedral mesh improvement using moving mesh smoothing, lazy searching flips, and RBF surface reconstruction
Franco Dassi, Lennard Kamenski, Patricio Farrell +1
Given a tetrahedral mesh and objective functionals measuring the mesh quality which take into account the shape, size, and orientation of the mesh elements, our aim is to improve t…
